If this product works as advertised, it’s pretty revolutionary. It used to be that if you wanted to spend any significant amount of time underwater you had to either stay close to the surface and snorkel, or don heavy scuba gear with a large oxygen tank. Well, the Triton mouthpiece changes all that. It contains “Microporous Hollow Fiber” with openings allegedly smaller than water molecules, but big enough to let oxygen through. A battery then runs a powerful micro-compressor that extracts and stores the oxygen in a tiny tank. This gives the wearer the ability to go up to 15 feet underwater for up to 45 minutes at a time with no other specialized equipment, breathing normally while simply biting down on the Triton. 15 feet may not seem like much, but that’s still deep enough to explore coral reefs and a bunch of underwater stuff normally out of reach. It seems too good to be true, but we’ll wait on initial reviews to come out before passing judgement. If it checks out, the $300 asking price is more than bargain.
